The d-amino acid (R)-2-amino-3-(7-methyl-1 H-indazol-5-yl)propanoic acid (3) is a key intermediate needed for synthesis of a drug candidate compound. Enzymatic routes to 3 were explored. d-Amino acid 3 was prepared in 68% isolated yield with >99% ee from racemic aminoacid 1 using l-amino acid deaminase from Proteus mirabilis expressed in Escherichia coli in combination with a commercially available
